概述引起逼尿肌活动过度的真正原因尚未探明。逼尿肌活动过度根据有无潜在的神经异常而分两种情况:逼尿肌高反射是逼尿肌不随意的或由于潜在的神经系统的作用使逼尿肌受收缩不受约束而漏尿;而逼尿肌不稳定则是原发的。无漏尿时,如逼尿肌收缩≥15cmH_2O,两者即可诊断。尽管老年更普遍,逼尿肌高反射大约仅为逼尿肌活动过度患者的10%。逼尿肌高反射或不稳定,或是由于前者能查明原因的神经性发作或原因不明的后者使膀胱失掉了正常的约束力,由于两种
Overview The true cause of detrusor hyperactivity has not yet been demonstrated. Detrusor hyperactivity can be divided into two situations depending on the presence or absence of a potential neurological abnormality: high detrusor reflexes are involuntary detrusor or urinary bladder leakage due to potential nervous system contractions ; And detrusor instability is the primary. No leakage of urine, such as detrusor contraction ≥ 15cmH_2O, both can be diagnosed. Despite the more common age, high detrusor reflexes account for only about 10% of patients with detrusor overactivity. Detrusor hyperreflexia or instability, or because the former can identify the cause of neurological attacks or unexplained the latter cause the bladder to lose the normal binding, due to two
